Parsing config file
Hi All,
I have a requirement to parse a file.
Let me clear you all on the req.
I have a job which contains multiple tasks and each task will have multiple attributes that will be in the below format. Each task will have some sequence number according to that sequence number tasks shld execute.
Code:
S.No. SeqNo# TaskID |Task Name | Attribute Name| Attribute Value1 1 1 | Java | classpath | sample.jar2 1 1 | Java | Runtime | -Xms -5123 2 2 | StoredPro | DB | sample.ini4 2 2 | StoredPro | ProcName | get_emp()
Like in the above format the infomation is written into the file.
The above job has 2 tasks (java, storedPro) with multiple attributes to each job. For example Java:- classpath, Runtime
I want to parse the file and and pick up the task and its attributes and execute as per the sequence number like java has to execute first with all attributes and stored proc fallows.
Please advice how can i achieve this.
Appriciate if any links or sample code.

LEARN ABOUT DEBIAN
jh_manifest
JH_MANIFEST(1) Javahelper JH_MANIFEST(1)
NAME
jh_manifest - Adds or/and modifies manifests for jars
SYNOPSIS
jh_manifest [debhelperoptions] [options] jar1 ... jarN
jh_manifest [debhelperoptions] [options]
DESCRIPTION
Javahelper tool to add or update manifests in a jar file. It can be used in two modes. If passed jar files, it will only process these jar
files. Otherwise it will update all jar files in the packages it acts on.
When processing a package, the debhelper(7) exclude option will make jh_manifest ignore matching jar files.
FILES
debian/package.manifest (or debian/manifest)
This file consist of a list of jar files and values to add to their manifests. Values in this file will take precedence over values in
the original manifest (and command line arguments over values in this file).
It is allowed to list a link in this file instead of an actual jar file, provided that the link can be resolved when jh_manifest
processes it.
If a jar file is listed here cannot be found, jh_manifest will print a warning, unless the jar file has been excluded.
As of javahelper >= 0.32, you may add comments in this file. If the line starts with a "#" it is completely ignored.
This file is ignored if jh_manifest is passed jar files via command line.
OPTIONS
-c classpath, --classpath=classpath
Sets the Class-Path attribute of all processed jar files to classpath.
If not passed, then the CLASSPATH environment variable will be used in the given jar file do not have a Class-Path attribute.
-m class, --main=class
Sets the Main-Class attribute to class in all processed jar files.
-o options, --javaopts=options
Sets the Debian-Java-Parameters to options in all processed jar files. This attribute is used by jarwrapper to start java with extra
options (e.g. to make more memory available).
-j /path/to/java/home, --java-home=/path/to/java/home
Sets the Debian-Java-Home attribute to /path/to/java/home in all processed jars. This attribute is used by jarwrapper to determine
which JVM to use.
EXAMPLES
An example debian/manifest file:
# use the symlink so we do not have to update with the next upstream release.
usr/share/java/my.jar:
Class-Path: dep1.jar dep2.jar
Main-Class: some.awesome.Class
usr/share/java/dep2.jar:
Class-Path: dep1.jar
SEE ALSO
debhelper(7)
This program is a part of javahelper and uses debhelper as backend. There are also tutorials in /usr/share/doc/javahelper.
